Definitions

  • the invention relates to compounds of the formula
  • R 1 and 2 are the same or different and denote hydrogen or an ester protecting group
  • R is hydrogen or an amino protecting group
  • R 4 is C 12-20 -alkyl, and its enantiomers, diastereomers and salts.
  • the invention in a further embodiment relates to a process for the preparation of the compounds of the formula I and to the use of the compounds of formula I in the solid phase peptide synthesis.
  • the compounds of the present invention have been found to be versatile peptide intermediates for the solid phase peptide synthesis (SPPS) of peptide drugs which comprise a Glu-fatty alkyl side chain building block attached to a Lys-part of the peptide chain.
  • SPPS solid phase peptide synthesis
  • Liraglutide can be mentioned, which is a GLP-1 analog diabetes-2 peptide drug.
  • Liraglutide carries a Glu -hexadecanoyl side chain building block at the Lys 26 position (Wikipedia, the free encyclopedia of 30.04.2012)
  • Object of the present invention is to provide novel peptide intermediates which carry a Glu-fatty alkyl side chain and which can readily be inserted in the SPPS.
  • R 1 and 2 are the same or different and denote hydrogen or an ester protecting group, R is hydrogen or an amino protecting group and R 4 is C 12 -2o-alkyl, and its enantiomers, diastereomers and salts have the potential to very well serve this purpose.
  • C 12 - 2 o alkyl used for substituent R 4 refers to a branched or straight-chain monovalent saturated aliphatic hydrocarbon radical of twelve to twenty carbon atoms, particularly to a straight-chain monovalent saturated aliphatic hydrocarbon radical.
  • the term can be exemplified by the radicals dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, nonadecyl and eicosanyl.
  • R 4 refers to Cu- ⁇ 6 alkyl, even more particularly to C 15 alkyl.
  • R 4 is tetradecyl, pentadecyl or hexadecyl, but particularly pentadecyl.
  • amino protecting group used for substituent R refers to common substituents conventionally used to hinder the reactivity of the amino group. Suitable amino protecting groups are described in "Fmoc Solid Phase Peptide Synthesis - A Practical Approach"
  • R is Fmoc (9H-fluoren-9-ylmethoxycarbonyl).
  • ester protecting group used for substituents R 1 and R 2 refers to any substituents conventionally used to hinder the reactivity of the hydroxy group. Suitable hydroxy protecting groups are described in Green T., "Protective Groups in Organic Synthesis", Chapter 1 , John Wiley and Sons, Inc. ,1991, 10-142 and can be selected from Ci-4-alkyl, optionally substituted with phenyl, C 2 -4-alkenyl, piperidinyl or dimethylaminoboranyl. Particular ester protecting groups for R 1 and R 2 are Ci-4-alkyl or C 2 _4-alkenyl.

  • R 1 t-butyl R 2 hydrogen, R 3 Fmoc, R 4 Qs-alkyl, particularly pentadecyl.
  • the compounds of the present invention can be prepared with processes which in principle are known to the skilled in the art of peptide synthesis.
  • the process comprises a) coupling the glutamic acid derivative of formula
  • R 1 and R 4 are as above, or a salt thereof with a lysine derivative of formula
  • R 2' is an ester protecting group and R 3 is as above, or a salt thereof to form a compound of the formula
  • Step a) requires the coupling of the glutamic acid derivative of formula II with the lysine derivative of formula III.
  • the glutamic acid derivative of formula II can be prepared following the scheme 1 below starting from commercially available starting materials.
  • a suitable commercially available glutamic acid derivative of formula II is the (S)-5- benzyl 1-tert-butyl 2-amino-pentanedioate hydrochloride.
  • the lysine derivatives of formula III are commercially available.
  • the (S)-allyl 6- amino-2-(((9H-fluoren-9-yl)methoxy)carbonylamino)-6-aminohexanoate is used.
  • the coupling of the glutamic acid derivative of formula II with the lysine derivative of formula III can then be performed applying the classical techniques for peptide synthesis.
  • the glutamic acid derivative of formula II is initially activated with an activating agent which is customary in the art such as with carbonyldiimidazole (CDI), carbodiimides selected from e.g. dicyclohexylcarbodiimide (DCC) or diisoopropylcarbodiimide (DIC) or triazols selected e.g. from 1-hydroxy-benzotriazole (HOBt) or l-hydroxy-7-aza- benzotriazole (HOAt).

  • a suitable organic solvent such as in diethyl ether.
  • Step b) requires the removal of the ester protecting group R 2' to form the compound of formula la.
  • a suitable system for removing the allyl group is for instance a solution of a Pd- source, like tetrakis(triphenylphosphine)palladium(0) and of phenylsilane in an organic solvent such as dichloromethane, tetrahydrofuran or methyl tetrahydrofuran.
  • a Pd- source like tetrakis(triphenylphosphine)palladium(0) and of phenylsilane in an organic solvent such as dichloromethane, tetrahydrofuran or methyl tetrahydrofuran.
